I know what you're thinking. "Did he fire six shots or only five?" Well, to tell you the truth, in all this excitement I kind of lost track myself. But being as this is a .44 Magnum, the most powerful handgun in the world, and would blow your head clean off, you've got to ask yourself one question: "Do I feel lucky?" Well, do ya, punk?

You just keep thinking Butch. That's what you're good at.

Not a classic, but I've always liked this one..

I feel I was denied... critical.... NEED TO KNOW.... INFORMATION.

I think it resonates with some software projects I've worked on

As for classics...   Bond. James Bond.

Elwood: It's 106 miles to Chicago, we got a full tank of gas, half a pack of cigarettes, it's dark... and we're wearing sunglasses. 
Jake: Hit it.

classic quotes.

"Hes more machine than man now..."

"Did you see anything?"

"No sir, I didn't see you playing with your dolls again."

"Who wants a mustache ride?"

"Hello. My name is Inigo Montoya. You killed my father. Prepare to die."

"You fell victim to one of the classic blunders - The most famous of which is "never get involved in a land war in Asia" - but only slightly less well-known is this: "Never go against a Sicilian when death is on the line"!"

"INCONCEIVABLE!"
"You keep using that word. I do not think it means what you think it means."

"Rodents Of Unusual Size? I don't think they exist."

Supervisor: Attention, whoever you are, this channel is reserved for emergency calls only.

John McClane: No f*ing sh*t, lady. Does it sound like I'm ordering a pizza?

Matt Farrell: You just killed a helicopter with a car!

John McClane: I was out of bullets.

"and why are you here?"

"BECAUSE WE ARE THE BEST OF THE BEST OF THE BEST. SIR!"

"And the Grinch, with his Grinch-feet ice cold in the snow, stood puzzling and puzzling, how could it be so? It came without ribbons. It came without tags. It came without packages, boxes or bags. And he puzzled and puzzled 'till his puzzler was sore. Then the Grinch thought of something he hadn't before. What if Christmas, he thought, doesn't come from a store. What if Christmas, perhaps, means a little bit more."

"You can't handle the truth!"

"Well, I generally come in at least fifteen minutes late. I use the side door - that way Lumbergh can't see me - and, uh, after that I just sorta space out for about an hour."
"Space out?"
"Yeah, I just stare at my desk; but it looks like I'm working. I do that for probably another hour after lunch, too. I'd say in a given week I probably only do about fifteen minutes of real, actual, work."

"The thing is, Bob, it's not that I'm lazy, it's that I just don't care."
"Don't... don't care?"
"It's a problem of motivation, all right? Now if I work my * off and Initech ships a few extra units, I don't see another dime, so where's the motivation? And here's something else, Bob: I have eight different bosses right now."
"I beg your pardon?"
"Eight bosses."
"Eight?"
"Eight, Bob. So that means that when I make a mistake, I have eight different people coming by to tell me about it. That's my only real motivation is not to be hassled, that and the fear of losing my job. But you know, Bob, that will only make someone work just hard enough not to get fired."
